What did you do to your mk7 today?

[StorableComa]

That's what happens, right before the shift. Injectors?

No, looking closer it looks like you're off the gas. Misfire at cyl 3 happens for a split second before you dump the accel pedal according to the log. Injector drops with accel, so normal. I feel like I'm blind, but everytime I look over your variables I'm not seeing misfire. I see knock.. And knock would be timing and/or fuel related at those RPMS. Which would point to tune to me.

I'm not mad about it. You saw what the Ruths looked like, they weren't for my setup.

Disagree. They looked fine.

 

[Acadia18]

Disagree. They looked fine.

Sure he doesn't have detonation?

Nevermind, you do have injector drop while still requesting WOT it looks like..

Alright, I'm gonna go log it and report back with a fresh log.

That's what I thought. Goes from 7K to 5.5K

 

[Diggs24]

Do I get to add some parameters to log...I mean if you're going to go log....

Your torque is doing something weird when all this happens. You request and were doing actual and at clutch of 400, then you get the injector drop at WOT and torque drops to 250 at clutch and actual. Are you completely off gas when clutching in, or clutching in while coming off the gas at the same time?

Sure, give er.

Just came back. Couldn't get it to replicate but it felt like it usually does right before it throws an EPC. I note the injection pulse dropping, albeit not as rapidly as in the misfire log.

I'm not sure? I may be a bit on the gas as I clutch in, but I'm fully off the gas before I engage the next gear.

So what’s the deal with Ruth’s not being cool on hybrid setups? Mine seem to be doing ok and Hoon didn’t say anything about them.

Get rid of these 6

https://datazap.me/u/daks/log-1663902946?log=0&data=9-10-12-13-14-15-44

Replace with these:

• Cylinder 1 - 4 SOI Primary Pulse Primary start of injection pulse per cylinder.
• Cylinder 1 - 4 SOI Secondary Pulse Secondary start of injection pulse per cylinder.
• Cylinder 1 - 4 EOI Limit End of injection limit timing per cylinder.
• Cylinder 1 - 4 Injector End Angle Primary Pulse Primary end of injection angle timing per cylinder.
• Cylinder 1 - 4 Injector End Angle Secondary Pulse Secondary end of injection angle timing per cylinder.
• Start of Injection Limit End of start of injection window.

If you really do get to pick a cylinder for all of those "cylinder 1-4" then I guess pick cylinder 3 for all of them.

Wind out 3rd again.

They're just not on EQT's official recommendation list.

Will do and thank you. Log coming tomorrow.

@Diggs24 I'm replacing the injectors anyway tomorrow. I'll give er with the new injectors in there, and then if the problem still occurs I'll do this.
